It is the successor of the Panasonic Lumix DMC-FZ30. While the FZ30 was a major upgrade of the FZ20 both internally and externally, the FZ50 differs relatively little from the FZ30. The main differences are:
The camera is known for its high-quality optics and effective optical image stabilization system. Many professional reviews have commended it for its excellent pictures at ISO 100, but it has a reputation for excessively "smeary" noise reduction at higher ISO settings, a problem that can be ameliorated by using the RAW capture mode. It uses proprietary lithium-ion batteries. There is no storage built into the camera; an MMC, SD, or SDHC memory card is required. High-speed SD cards up to 2 GB and SDHC cards up to 32GB are supported. The camera has many SLR-like handling features — dual control wheels for aperture and shutter speed, manual focus (focus-by-wire) and zoom rings, and a flash hot shoe. It is among the largest non-SLR cameras built, and is positioned at the high end of the bridge-camera market. Zooming while recording movies is supported since the zoom is manual. The camera also includes an "extended optical zoom" system providing greater optical zoom ability when shooting at lower resolutions, giving up to 19.3× zoom at 3MP. Essentially, this just crops the center out of the image in-camera, but can be useful for metering and framing purposes. Apertures from {{f/}}2.8 to {{f/}}11 are supported, though the largest apertures are not available at high zoom levels ({{f/}}3.7 at full zoom). Shutter speeds range from 60 s to 1/2000 s, although shutter speeds faster than 1/1000 s are not available at the widest apertures. Several different auto-focus modes are available. The AF-macro setting can be selected for all camera modes. Macro capability is not outstanding (5 cm minimum focal range at 1× zoom), and the tele-macro capability present on the lower-end Panasonic FZ models (the ability to focus down to 1 m at 420 mm) is not present; the FZ50 can only focus down to 2 m at 420 mm. However, the FZ50 is commonly used to record high-magnification macro images with an inexpensive conversion lens; the most commonly used lens for this purpose is the 8-diopter Raynox 250. The FZ50 has a screw mount to accept 55 mm filters, and is compatible with a wide variety of Panasonic-branded and third-party lens converters which can provide greater wide-angle, telephoto and close-up capabilities. The FZ50 can also record in a RAW format which is supported by Adobe Camera Raw and the free UFRaw plugin for GIMP and many other third-party programs; the camera comes with a special version of Silkypix for conversion. RAW files are recorded in around three seconds with fast SD cards, which is one of the best results among non-digital single-lens reflex cameras; however, there is no RAW buffer as on many digital SLR's. Unlike its predecessors, the FZ50 does not support TIFF format. The zoom and focus mechanism is internal: the lens does not physically extend beyond the camera housing when focusing and zooming. Startup is under one second, as the lens does not need to be extended. See also
